A cylinder contains 2 lbm of an ideal gas wth a gas constant Rof 53 ft lbf/lbm oR. The gas is initially at agauge pressure of 30 psi and temperature 100 oF. It is heated at constant volume until it reaches a temperature of300 oF and is then allowed to expand at constant pressure until its volume doubles. What is the pressure of the gas (psia) at the end of the heating process? What is the final temperature of the gas (oF) at the end of the expansion.
